Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2023The c.1226G>A (p.R409Q) alteration is located in exon 5 (coding exon 5) of the TRPC7 gene. This alteration results from a G to A substitution at nucleotide position 1226, causing the arginine (R) at amino acid position 409 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
